HOMER R. AIJKIRE, F MOUNT STERLING, OHIO.

CULTIVATOR.

Specification of Letters Patent.

Application iled July 1g, 1910. Serial No. 572,170.

To all whom it may concern:

Be it known that I, l-IOMER R. ALKIRE, a citizen of the United States,residing at Mount Sterling, in the county of Madison and State of Ohio,have invented certain new and useful Improvements in Cultivators, ofwhich the following is a specification.

This invention relates to farm implements, and is designed particularlyto construct an improved cultivator which will be inexpensive, simple,and durable in construction.

It also contemplates the construction of a cultivator wherein the draftwill be applied directly to the cultivator beams and also to construct acultivator whereby the tongue may be swung in order to aid in guidingsaid cultivator.

With the above and other objects in view, this invention consists in theconstruction, combination, and arrangement of parts, all as hereinaftermore. fully described, claimed, and illustrated in the accompanyingdrawings, wherein- Figure 1 is a top plan view o-f a cultivatorconstructed in accordance with the Vpresent invention; Fig. 2 is acentral longitudinal section thereof; Fig. 3 is an elevation of the archto which the cultivator beams are secured.

Referring more particularly to the drawings 10 indicates a rectangularframe having a seat 11 at the rear terminal thereof and the forward end12 thereof curved. An axle 13 is centrally and rigidly mounted to theframe 10 through the instrumentality of the bearings 14 carried on theunder side of said frame. The outer terminals of said axle haverotatably and adjustably mounted therein the crank axles 15 at the outerterminals of which are rotatably mounted the wheels 16. A base plate 17is centrally secured to the curved end 12l of the framelO through theinstrumentality of ears 18 with which the plate 19 cooperates. `Thetongue 20 is pivotally mounted between the plates 17 and 19 through theinstrumentality of the pin 21, said tongue being adapted to swing aboutsaid pivotal point. A track 22 is interposed between the sides of theframe 10 and curved in an opposite direction to the curve of the end 12of said frame, said track adapted to receive a grooved roller 23 carriedby the inner terminal of the tongue 20, thus forming the support fo-rthe terminal of said tongue and also a guide to insure the directoperation thereof. A bracket 24 is secured centrally to the track 22 onthe side thereof opposite to the tongue 20 and has pivotally mounted atthe terminal thereof the arm 25 which is provided at each terminal witha slot 26, the slot in the forward terminal thereof engaging a pin 27carried by the inner extremity of the shaft 20. A platform 28 isinterposed between the sides of the frame l() directly in front ofthefseat and carries adjacent the forward edge thereof the verticalpivot 29. To this vertical pivot' 29 is connected a link 30, said linkhaving on each'side thereof a foot rest 31 and a chain 32 at its outerterminal, said pin kengaging the slot 26 in the rear terminal of the arm25.' From this construction it will be understood that as the foot rests31 are shifted one way or the other the tongue 20 will likewise beshifted, thus greatly aiding in the steering of the present invention.`A shaft 33 is mounted` on the under side of the frame between the track22 and the curved end thereof, said shaft having .the terminals 34thereof bent downwardly and connected to the axles 15 by the links 35. Alever 36 is rrigidly connected to the shaft 33 adjacent one terminalythereof and cooperates wit-h the quadrant 37, said lever being adaptedto regulate the height of the frame 10 above the ground. An auxiliaryconnection or brace 38 is interposed between the lever 36 and one of theterminals 34 of the shaft 33, thereby insuring a positive connectionbetween said lever and said shaft. In order to aid in operating thelever 36 a spring 39 is interposed between each of the downwardly bentport-ions 34 of the shaft 33 and the sides of the frame 10. The bar 40is mounted on the under-side of the frame 10 adjacent to the forwardterminal 12 thereof and is provided with a downwardly projectingextension at each terminal there- These extensions 41 support at theirlower terminals the arch 42, said arch being bent horizontally to formthe bearing shafts 43 to which the lower terminals of the extensions 41are secured.4 A sleeve 44 is mounted on each of the'bearing shafts 43and has a rearwardly extending projection 45 on the inner side thereof,said projection having a vertically extending tube 46 formed thereon.The cultivator beams 47 are secured to the tubular members 46 by theyokes 48 through which the bolts 49 extend, thus mounting said beam forlateral movement. On the outer side of t-he extensions 41 on each shaft43 is mounted a collar 50 to which the draft mechanism is secured ashereinafter more fully described. The bar 5l is mounted on the underside of the curved terminal 12 of the frame l0 directly under thepivotal point of the tongue 20, said bar having the downwardlyprojecting extension 52 formed at each terminal thereof. The lowerterminals of t-he extension 52 are connected by the resilient links 53to the collars 50 and have on the opposite sides thereof the hooks 54 towhich are secured the draft mechanism.

In order to provide a means whereby the cultivator beams 47 may beraised and lowered a lever 55 is mounted on each side of the frame 10and cooperates with the quadrant 5G, said levers being connected to thecultivator beams 47 through the instrumentality of the resilient link57. Thus upon operating t-he levers about the quadrant 56 the cultivatorbeams 47 will be swung about the shaft 43 of' the arch as an axis. F romthis construction it will be readily understood that the pull is exerteddirectly upon the cultivator beams and not through any intermediateelement.

I-Iaving thus fully described my invention what is claimed as new is:

In a device of the class described, the combination with a rectangularframe, of wheels carried thereby, a U-shaped cultivator supporting rodcarried on the under side 7of said frame adjacent to the forwardterminal thereof, an arch disposed within said U- shaped supporting rodfor the terminals thereof bent outwardly and mounted in the terminals ofsaid rod, sleeves loosely mounted on the bent portions of said archadjacent to the inner surfaces of the terminals of said rod, a verticaltubular bracket carried by the rear sides of said sleeves, cultivatorbeams, vertical yokes carried by said cultivator beams adapted to spansaid t-ubular brackets, pins pivotally securing said yokes to saidbrackets, collars loosely mounted on the bent portions of said arch onthe exterior of the terminals of said rod, a transverse bar carriedunder the forward extremity of said frame, downwardly extendingprojections formed at each terminal of said bar, resilient connectionsbetween said collars and the lower terminals of said extensions, leversmounted on said frame above said cultivator beams, and resilientconnect-ions between said levers and said beams.

In testimony whereof I afi-ix my signature in presence of two witnesses.
